IMPROVEMENT IN NUT-LOCKS.

S'pecfication forming part of Letters Patent No. 148,328, dated iWaroh 10, 1874; application filed A December 23, 1873.

To all whom it may concern:

Be it known that I, SIMnoN RUMMEL, of Leetonia, in the county of Golumbiana and State of Ohio, have invented a certain new 'and useful Improvement in Fish-Joint for Railways 5 and I do hereby declare that the fol= lowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereor'.

Myjnvention relates to an inprovement in nut-lock for the bolts used in connection with fish-bars for conpling together the rails of rail- Ways; and consists in the combination of a grooved bar With the fish-bar bolts and nuts.

To enable others skilled in the art to make and use my invention, I Will proceed to describe its construction and operation.

In the accompanying drawings, which form part of my specification, Figure 1 is a side elevation of a section of a rail for railways provided With my improvement for looking the nuts used in connection with bolts and fishbars. Fig. 2 is a vertical and transverse section of the same at line w of Fig. 1.

A represents the rail, and B the fish-bar. O represents the bolts, and D their screW-nuts. frepresents a bar, the npper side of Which, near its edge, is provided With a groove, e,

into which is fitted the lower edge of the fish= bar Bi As the construction of the several parts and their arrangement with relation to each other Will be readily understood by reference to the accompanying drawings, I Will, therefore, proceed to describe the operation, Which'is as folloWs:

The rails are joined together in the usual manner, and coupled through the medium of the fish-bar B, bolts O, and screW-nuts D, in the ordinary Way, after Which thebar f is placed on the Web of the rail A, With the lower edge of the fish-bar B entering the groove e. The bar f is then driven under the fish-bar, as inf dicated in Fig. 1, Which Will prevent the nuts V D from turn'ing on their bolts O, and also add greatly to the streng'th and firmness of the fish-j oint.

Having thus described my inprovement, What I clain as of my invention is- The combination of the grooved bar e, forming a dovetail projection, the fish-bar B, constructed as described, and bolts and nuts, for forming the joints of railways, substantially as described.
